Abstract:
Overall losses in swash plate type axial piston machines are mainly defined by three
tribological interfaces. These are swash plate / slipper, piston / cylinder and cylinder
block / valve plate. Within a research project, funded by the German Research
Foundation, a combined approach of experimental research and simulation is chosen
to acquire further knowledge on the cylinder block / valve plate contact. The
experimental investigations focus on the friction torque within the contact and the
measurement of the cylinder block movement in all six degrees of freedom.
Simultaneously a simulation model is created focusing on the main physical effects. By
considering the results of the experimental investigations significant physical effects for
the simulation model are assessed. Within this paper the implemented effects are
described and a first comparison between experimental results and simulation is
presented.
